often the most revolutionary ideas are born of intuitions so simple that they may perhaps be considered obvious, therefore neglected. But not for everyone. This is the illuminating case of Reyahn Jamalova: 15, a student at the Istec Institute in Baku, Azerbaijan, she wondered why "if you can create energy from the wind, you can not do the same with rain?". This is how Rainergy was born, an intelligent device capable of generating electricity from rainwater and which promises to be the solution to the energy problem of developing equatorial countries.
Jamalova and his classmate, Zahra Gasimzade, took four months to develop the idea, with the support of their physics teachers and state funding: in fact, the Azeri government itself believed in the potential of research, deciding to invest in the project $ 20,000. A modest sum for what promises to be one of the best energy solutions for the future, especially those developing countries characterized by a rainy climate, primarily Asian neighbors such as the Philippines, India, Malaysia and the Indonesia. In fact, according to the World Traceability Standard 2014 report, 21% of the Indian population and 11% of the Filipino population do not have access to the electricity grid.
But how does Rainergy show up and work? At nine meters height, this luminaire has four essential components: a rainwater collector, a tank, an electric generator and a battery. The collector fills the rainwater tank, which circulates at high speed through the generator, producing energy; this is stored in the battery, thus cushioning the overload of the local electricity grid and providing an additional source of energy to the communities. The relatively simple design of the invention makes Rainergy highly competitive compared to other renewable energy sources - solar panels, wind turbines, piezoelectricity. Also for this reason the device has depopulated, receiving also an honorable mention to the Model UN Conference in Azerbaijan and arriving at the final stage of the competition at ClimateLaunchpad, the largest European competition for business ideas.
